The mother of the boy identified as Victim 1 in the Penn State sex abuse scandal said her son broke down in tears when he heard accused child molester Jerry Sandusky claim on television they were just "horsing around."

Sandusky surprised many Monday night when he phoned in to NBC's Bob Costas. During the interview Sandusky denied all of the 40 charges of child sexual assault that have been leveled against him, and said that he is not sexually attracted to young boys.

"I could say that I have done some of those things," Sandusky said. "I have horsed around with kids. I have showered after workouts. I have hugged them and I have touched their legs without intent of sexual contact," he said. "Am I sexually attracted to underage boys? Sexually attracted, no -- I enjoy young people, I love to be around them ... but no, I am not sexually attracted to young boys," Sandusky replied to Costas.

The mother of Victim 1 said that there is no way what went on between her son and Sandusky was just horseplay.

"No, it's not games. It's a planned out strategy to groom children to molest," she said. "He definitely shouldn't have showered with those kids. It was sickening, I mean I don't know anybody -- anybody -- who when somebody's like 50, would get in a shower naked with a 10-year-old."

Her son was 10 or 11 when he first met Sandusky in 2005 or 2006, and the former coach lavished presents on him, including clothing, a computer, cash and trips, the grand jury report claims. It also charges Sandusky with molesting the boy more than 20 times.

The mother said she's angry to see Sandusky a free man while she and her son, who is now a teenager, feel they must hide to protect their anonymity.

"It's very difficult for me and for my son. We spend most of our lives since this has started hiding, trying to avoid getting chased down by press, his identity being revealed, dealing with the bullies at school," she said.

"He has to leave school pretty consistently to take medication because he can't he just can't stay there and listen to it," she said.

"It makes me really mad that my son can't go out and have a normal life. He can't go out and hang out at the mall, because he might run into Jerry. [Sandusky] gets to go to the mall and shop and do whatever he wants to do. That aggravates me. He should be in jail," she said.

Victim 1 is expected to be a star witness against the former coach.

"He's scared, but he's anxious. He's ready, he wants to do it....He wants to put it to rest. He wants him to go to jail and he wants him to pay for what he's done. And he doesn't want him on the streets where he can hurt somebody else," the boy's mother said.
